Silencer for firearms

Abstract

A silencer for use with pistols with a fixed or tilting barrel. The design configuration is such that the sighting line is retained when the silencer is fitted. Handleability of the weapon is not seriously adversely affected by the design configuration and the lightweight structure.

We claim: 
     
       1. A hand gun-silencer combination comprising: a hand gun having a gront sight disposed at the front end of the hand gun and having a barrel; a closed silencer housing defined by a peripheral wall having an outside surface and first and second end walls arranged at a spacing from eath other, said first and second walls being disposed entirely forwardly of said front sight, with a center line extending in the longitudinal direction of the silencer housing; an entry opening into the silencer housing having a longitudinal axis, said entry opening provided in the first end wall operative to receive a front open end of said barrel; a discharge opening from the silencer having a longitudinal axis, said discharge opening arranged in the second end wall, wherein the longitudinal axes of the entry and discharge openings are arranged to extend in aligned extension relative to a longitudinal axis of the barrel received in the front open end; means for mounting the silencer housing to the hand gun including arms extending from said first end wall into engagement with said hand gun; and wherein the longitudinal axes of the entry opening and the discharge opening are arranged eccentrically relative to the center line of the silencer housing and are at a spacing from an outside surface of the peripheral wall which is equal to or less than the spacing between the longitudinal axis of the barrel and a base of the front sight. 
     
     
       2. A combination according to claim 1 wherein the silencer housing has an annular confituration. 
     
     
       3. A combination according to claim 1 wherein the silencer housing compriser two peripheral wall portions which extend in parallel relationship at a spacing from each other and which are connected together by means of arcuate peripheral wall portions. 
     
     
       4. A combination according to claim 1 wherein the discharge opening is formed by a Borda3 s mouthpiece which projects into the interior of the silencer housing and which has a slightley larger inside diameter than the diameter of the bore of the barrel. 
     
     
       5. A combination according to claim 1 wherein the end fo the barrel is accommodated with slight clearance between a peripheral wall of the barrel end and a peripheral wall of a bored-out portion of the entry opening. 
     
     
       6. A combination according to claim 5 wherein the front end of the barrel is accommodated in an axial extent in the bored-out portion, which corresponds at least to the recoil travel of the barrel with or without a drop barrel. 
     
     
       7. A combination according to claim 1, wherein said arms include two arms arranged at the first end wall which are disposed in mutually opposite and spaced apart relationship, with bars disposed on the arms, wherein the bars are designed to be introduced into grooves on the hand gun casing. 
     
     
       8. A comgination according to claim 7, including a barrel holding pin wherein said arms at their free ends, which are towards said barrel holding pin, have arresting levers with hooks, which arresting levers are pivotable about a pin by means of springs. 
     
     
       9. A combination according to claim 8 wherein the barrel holding pin includes abutment surfaces and wherein the hooks cooperate with the hand gun casing and are brought into engagement with said abutment surfaces. 
     
     
       10. A conbination according to claim 1 wherein the silencer housing includes at least two chambers formed by a partitioning wall disposed in the silencer housing, wherein the partitioning wall has at least one through opening for the transmission of the gases from one chamber into the other and an aperture for a projectile to pass therethrough. 
     
     
       11. A combination according to claim 10 wherein the partitioning wall is accommodated between two sleeves which are respectively supported against the first and second end walls. 
     
     
       12. A combintaion according to claim 10 wherein said first and second walls of the housing are releasably in engagement together with the peripheral wall. 
     
     
       13. A combination according to claim 12 wherein the peripheral wall bears against stepped, mutually oppositely disposed recesses on the first end wall and the second end wall, and wherein the first and second end walls are screwed relative to each other by means of a screw device which passes thorugh the silencer housing. 
     
     
       14. A combination according to claim 13 wherein the partitioning wall is arranged at the screw device.
